[0027] According to the above table, the first connecting plate 462
and the second connecting plate are made of PP plastic materials,
which achieves effects of environmental protection and no odor.
[0028] The present disclosure provides the flexible medical
scissors, and the flexible medical scissors are operated in
following manner.
[0029] First, when the flexible medical scissors are to be used,
the flexible medical scissors are first sterilized, then a user
holds the handle 2, and puts a ring finger of the hand holding the
handle 2 into the finger sleeve 31 in the lifting mechanism 3, and
then operation is to begin.
[0030] Second, when it is necessary to operate the shearing
mechanism 6, the inner ring finger have a backward dragging force,
so that the finger sleeve 31 drives the rubber rope 32 to pull the
pull rope 33 to pull the winding column 10 at the top of the
rotating shaft 9, and then the winding column 10 rotates to drive
the rotating shaft 9 at the bottom to drive the movable cutter 7 to
move for a work, so that when the movable cutter 7 needs to be
closed, only the finger sleeve 31 needs to be retracted, and since
the lower end of the pull rope 33 is the elastic segment, the
winding column 10 is retracted, and the rotating shaft 9 makes the
movable cutter 7 fallback and close.
[0031] Third, when it is necessary to enter a penitent body for
operation, the movable cutter 7 needs to be closed to enter the
patient body, and then it is determined according to bending of
blood vessels when it is necessary to bypass important blood
vessels and nerves, the user slides the sliding columns 44 in the
sliding grooves 42 using the ring finger, and the sliding columns
44 may pull the wire columns 464 of the rotation shafts 463 in the
second connecting plates 465 through the pull wires 45 and bend the
second connecting plates 465 through rotation of the rotation shaft
463. The clamping grooves 43 are disposed in the sliding grooves
42, and when the sliding columns 44 are fixed in the clamping
grooves 43, an adjusted angle may be fixed. After the second
connecting plates 465 are adjusted, the flexible sleeve 5 may be
bent to achieve an effect of bypassing the important blood vessels
and nerves. Retracting the sliding columns 44 may retract the
second connecting plates 465. When it is necessary to adjust
positions of the fixing plates 461 and the first connecting plates
462, according to the adjusting method of the second connecting
plate 465, the sliding column 44 in the sliding groove 42 in the
middle may adjust the positions of the first connecting plates 462,
the sliding column 44 in the sliding groove 42 in the right may
adjust the positions of the fixing plates 461, and the flexible
sleeve 5 may be bent at different angles, so as to bypass the
important blood vessels and nerves according to the natural gaps of
the human body tissues and lesions are reached in a roundabout way
for surgery operation.
[0032] Fourth, when the main body 1 needs to extend into a surgical
channel to enter the human body, the user releases elastic force of
the telescopic pull wire 21 through the connecting block 25, then
falls into a bottom of the adjusting groove 23, and the spring 20
at the bottom may release the pushing force, so that the shearing
mechanism 9 extends into the human body, when the main body needs
to be retracted, the telescopic pull wire 21 is pulled back through
the connecting block 25, so that the second fixing disc 8
compresses the spring 20, then the connecting block 25 is slid into
the fixing groove 24, and adjustment of different lengths is
achieved. After entering the human body, an angle of the shearing
mechanism 9 needs to be adjusted to achieve an optimal shearing
angle of the lesions, and then the user may pull the clamping block
18 to enable the connecting wire 17 to adjust the movable ball 27,
and since the movable ball 27 slides in the annular groove 26 and
may slide to the required angle, adjusting in multiple angles may
be realized by pulling the movable ball 27.
[0033] The flexible medical scissors provide the lifting mechanism
3 at the top of the handle 2, the finger sleeve 31 in the lifting
mechanism 3 sleeves the ring finger of the user, when using, the
finger sleeve 31 is pulled to enable the pull rope 32 to pull the
rotating shaft 12, and the rotating shaft 12 drives the movable
cutter 10 to rotate, so that a shearing function is realized. The
adjusting mechanism 4 is disposed at the bottom of the handle 2,
the three groups of the sliding grooves 42 are formed in the
adjusting mechanism 4, and sliding columns 44 are respectively
disposed in the sliding grooves 42. When the sliding columns 44 are
slid to different positions in the sliding grooves 42 to fix, the
three groups of the rotation shafts 467 in the adjusting plates 46
are pulled through the pull wires 45, so that two groups of the
connecting plates have different connection angles, and the
flexible sleeve 5 may be bent at different angles. The spring 20 in
the shearing mechanism 9 is controlled by the telescopic pull wire
21 to control a length of the shearing mechanism 9, so that the
surgical channel may conveniently enter the patient body. In
addition, the adjusting disc 19 is disposed at the upper end of the
shearing mechanism 9, after the user pulls the connecting wire 17
according to an angle, the shearing mechanism 9 is adjusted in
multiple angles and in all directions, so that the important blood
vessels and nerves may be bypassed according to the natural gaps of
the human body tissues and the lesions are reached in the
roundabout way for the surgery operation.
